Lamp height adaptor



INVENTOR ATTORNEY Filed March 25, 1957 f l 1 l l f 3,015,025 PatentedDec. 26, 1961 3,015,025 LAMP HEIGHT ADAPTOR Evan T. Williams, 755Central Ave., Westfield, NJ. Filed Mar. 25, 1957, Ser. No. 648,314 6Claims. (Cl. 24d- 144) This invention relates to lamp height adaptors,and more particularly to devices of this character for adjustablyraising or lowering lamp bulbs or shades with respect to the lamppedestal or base.

Lamp pedestals are manufactured in different heights, and it isnecessary for the distributor to carry in stock such different heightsfor each design of pedestal, resulting in a large inventory.Furthermore, when a particular height is selected, it may be found to betoo high or too low for a chair or table or other furniture with whichit is to be grouped.

It is therefore the main object of the present invention to provide aheight adaptor for a lamp pedestal to adjust the lamp bulb or shade tothe desired height without changing the pedestal and without the use ofspecial tools. l

Lamp pedestals are generally provided with a holder containing a lampsocket and having a flange for supporting a glass reflector surroundingthe bulb. This reflector flange has become standardized, generally to atwo and a quarter inch diameter. However, the reflector art isdeveloping to a new and improved reflector having a lower rim requiringa larger diameter, about two and five eighths inches.

It is therefore another object of the present invention to pro-vide anadaptor to fit into the old standard smaller diameter flange and havinga larger diameter reflector supporting flange to receive the newoversize reflector rims.

According to the present invention, the height extension adaptorcomprises a shell having a lower smaller annular flange of greaterdiameter than the lamp bulb socket or switch and an upper annular flangeadapted to receive the bottom of the glass shade rim at a greaterheight. The smaller annular flange preferably slidably receives anextension sleeve fitted over the lamp socket or switch. The extensionsleeve is preferably slidably received in a spacer ring fitted insidethe shade or reflector receiving flange of the pedestal holder. The eX-tension sleeve may be slotted for wires connected from the lamp switchto sockets on a ring slidably mounted on the extension sleeve. The topof the extension sleeve may telescopically receive a smaller tube forsupporting a lamp shade at an adjustable height.

In the drawings:

FIG. 1 is an elevation of a lamp pedestal provided with a height adaptoraccording to the preferred embodiment of the present invention;

FIG. 2 is an enlarged vertical section through the adaptor shown in FIG.l; and

FIG. 3 is a similar section through a different assembly of parts shownin FIGS. 1 and 2, other parts being omitted.

The lamp base pedestal shown in the drawings comprises a base supportinga stern 1.2 on the upper end of which is mounted a holder 14. The holder14 is an inverted bell shaped shell containing a lamp socket 15 andflaring upwardly and outwardly and terminating in an upper annularflange 16 adapted to receive the bottom rim of a standard gass reflectorsurrounding the lamp bulb 19. The flange 16 is provided with securingmeans such as set screws 2li for retaining the standard reflector inposition.

As shown in FIGS. 2 and 3, the height adaptor comprises a shell 22having a lower smaller annular flange 24 the inner surface of which isof greater diameter than the lamp socket 15, and an upper largerdiameter flange 25 adapted to receive the larger diameter rim of thereflector 18, and provided with securing means such as set screws 26 forsecuring the reflector rim therein.

The height adaptor may also comprise a spacer ring 28 as shown in FIG.2, which has an outer annular flange 29 the outer surface of which iltsinside the holder flange i6 and is secured in position by the set screws20. The Spacer ring 28 has an inner flange 30, the inner surface ofwhich slidably receives an extension sleeve or tube 32 such as a lengthof pipe of the same material and finish as the lamp pedestal. The sleeve32 and the inner flange 3f) are both of larger diameter than the lampsocket 15 so as to llt down thereover inside of the holder lll, thebottom of the sleeve being slotted as at 33 to receive the socket switchbutton 34. The set screws 20 are preferably of sufllcient length to passthrough both flanges 29 and 30 of the spacer ring, to engage the sleeve32 and secure it in position.

To bring the lamp bulb 19 above the top of the sleeve 32, one or moresocket extensions 35 are screwed into the socket 15 or precedingextensions. The adaptor shell 22 is mounted on the upper end of thesleeve 32, the smaller shell flange 24 slidabfy receiving the sleeve,and held at a selected adjusted height thereon by set screws 36.

When assembled as shown in FIG. 3, the adaptor shell is applied with itslower inner flange 24 inside the holder flange 16 and secured inposition by set screws 20 engaging a groove 38 in the outer wall of theadaptor shell. For this small increase in height, the extension sleeve32 is omitted, but a socket extension 35 is necessary to bring the lampbulb 19 above the upper adaptor flange 25 which holds the reflector 18.
